Application filed April 7, 1899, Serial No. (12,049.

To all whom it may concern: Be it known that I, FRANK H. BroKrom), a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in CashRegisters, of which I declare the following to be a full, clear, and exact description. This invention relates to improvements in cash registers andhas more particular relation to improvements in the class of machines patentedto Frank H. Bickford, Au ust 31, 1897/and numbered 589,114 and Cl ealand Reinhard, No.- 580,378,- April 1'3, 1897.

In the type ofmachines above referred to, and as illustrated in the present drawings, the left ha-nd bank of keys is divided into keys of two-classes, the three lower keys of the same representing the special transaczo tions such as Paid out Charge and Received onlaccountj while the remaining keys ofthe bank represent amounts, clerks initials or anything that may be desired.

As the present-lnvention relates only to the threelower special keys and their connections with the s ecial indicator hereinafter described I will iimit my description to the same and refer to the aforesaid patents for a detail description of the remaining parts.

a One: of the several objects of the nvention is to 'rovide a machineof the class mentione with an im roved special indicator for indicating the c aracterof each transaction whether it be a cash, credit, vpaid out or Specification of Letters Patent.

3 the regular indicators and 4 the special indicator extending transversely above the regular indicators.

.The regular keys, registering mechanism regular indicators and printer operate substantially as set forth. in the aforesaid patent of Oleal and Reinhard. The s 661711 transaction keys also cooperate with t rcir respective counters as shown in the said patent to Frank H. Biokford and in addition are pro- 'vided each with a laterally projecting pin These pins are so located as to project into roximity to the periphery of a segmental ever 7 which is suitably pivoted on the frame 1 and is provided at its rear end with a segmental rack 8. This rack meshes with a partial gear 9 formed on a sleeve 10 so as to impart movement to said sleeve according to the degree of movement of said lever. As will readily be seen "by reference to the drawings,

The aforesaid sleeveflO carries a special printing segment 13 which cooperates with the regularrmting device to print .a character. designatmg the character of the transaction as repre sented by the three special keys. Said sleeve is further providedwithatoothed stop and alining segment 14 which is adapted e enpaged by apaw1'15. ivoted u on esrnain; rame and normally eld outQ ngagergientwhich connects-1t with -..t he j. main. frame- Thi's-pawl isarran'gedto be forced in flieny upon w 'chiit-"rests and who granted 11 ii the outer end of;thef iisu ed ffrom'the-above that when r a lreys'is-ppemte esle v 10.. w ap ns W1- he.

The said segment 8 is provided with an car 19 to which is pivotally connected the lower end of a bar 20. This bar is also pivotally connected at its u per end to a short lfiv'fll 2]. which is pivoted at its lei t hand end (Fig. l) uponone of two vertical standards 30 and is rovided at its right hand or free end with a "jects into an elongated. slot 23 formed in a slide 24; screws 25 pass through other elon gated slots 26 formed in said. slide and screw into the main frame whereby said slide is held movably in position upon the frame. The upper end of said slide is formed with a rack- 27 which meshes with a inion 28 fast upon one end of a transverse s1aft 29 which is journaled in the standards 30 mounted on the main frame at its opposite sides. A horizontal cylindrical indicator 4 is mounted fast on said shaft 29 and is provided at diametrically opposite points uponits outersurface with similar characters for designating the respective special transactions as Well as the cash transactions; a suitable indication of which latter transactions must bedisplayed when neither of the special keys is operated and the special indicator is in normal osition. A spring 31 connects the said rac bar to the main frame so as to normallyjdraw' the slide 24 downward and thus leave the cash indications or characters exposed through the sight I openings in the front and back of the casing 32 which surrounds the said indicator 4.

Theslide 24 is further formed with a series of alining teeth 33. which are arranged to be --sprmgis mounted about a stud 36 on. the

back of the pawl while its opposite end is sup' ported by a similar stud mounted on a racket 37 secured to the main frame. The lower end of the pawl is provided with a pin 38 which is arranged in the path of a cam arm 39 mounted rigidly on a shaft 40 which is connected to the movable parts of the niachine so as to be oscillated during each operat1on thereof as follows: A' pendent spring pressed arm-40 is mounted on said shaft 40- at its op JOSltG end and is provided with a pin. 4O who is engaged and oscillated by a cam 40 fast on the shaft 18 whichlatter receives motion through suitable gears which connect it with the operating crank handle (see Fig. -5). I

When one of the special keys is operated the bar20 is forced upward as before d cscri bed and thus raises the lever 21 and the pin 22 so that the latter moves to the upper end of the slot 23 and raises the slide 24. The above described action results if the slide is m one of its lower positions and the lastspe- This pin pro can only be set by a further raising of said the slide to one of its upper positions the subsequent operation of a key governing a lower position of said slide will simply raise the pin. 22 in the slot Should the o crating handle now be operated the pawl 34- is disengaged from the alining teeth. which allows the slide 24 to descend under the impulse of the spring 31 until it is stopped. by the pin 22 abutting against the upper end of the slot 23. The releasing movement of the pawl 34 is effected during the initial movement of the operating handle so to permit the slide 24 to descend if the operated key demands such action. Subsequently during the same operation of the machine the pawl 34 is allowed v to again engage the rack teeth of the slide to Hook the latter in position. As the keys 2, 2 -are independent of the remainder of the keys of the bank in which they are located and do not cooperate with. the detent of the same it is necessary to provide means for locking said keys in their depre sed positions and for preventing the succi ve operation of more than one of said-keys during a single operation of the machine. I accom lish the first shown in Fig. 1, and in detail in Fig. 4 and which is secured movably in position by screws 42 which pass loosely through suitable-slots 41 formed. in the ends of said dotents. This detcnt is further formed with notched recesses 43 each having an incline wall 43 u and extension 44 having 4 an incline wall 45. The studs'or pins 5cxtcnd in. alinement with the recesses 43 sothat when one of the special'lreys is operated. the sleeve 6 of its stud will contact with the incli no wall 43" of its respective and thus raise said detent 41 against the tension of a spring 46 which connects it to the main frame, until the stud reaches the notched portion of the recess in which it becomes seated and locked by the detent being drawn down. over the same by its spring. The subsequent raising of the detent is accomplished by means of a slidablc latch bar 47 formed. with. elongated slots 4.8; one for the reception. of the main shaft 49 and the other for the reception of a guiding screw or pin 50. The said bar 47 is formed. near its forward end with a recess 51 having an incline wall 52 and arranged to receive the projection 44 of the said segment. The bar is normally drawn rearward by a coil spring 53 which connects a rearwardly ex tending arm 54 of the same to the main frame. This arm projects into the path of a cam 55 mounted upon the rotation shaft 18 so that said bar is forced forward against the tension of its s nrin upon each operation of the machine.

slidc.' When a previous indication has raised object by means of a movab c detent 41,

he forward movement of. the bar causes the incline wall 52 of recess 51 also with. an operating! which has been to contact with the incline wall 45 and thus raises the segment 41 and releases the key rcviously operated. In order to prevent the consecutive o eration of two or more of the special keys 2 uring a single operation of the machine I provide a stop segment 56 shown in detail in Fig. 4. This segment is slidably mounted in the same manner as the segment 41 and is located beside the same so that the pins 5'will roject into alinement with incline slots 57 ormed in said se ment.

, slot and move the segment upward which.

- its normal It will e seen by reference to the draw-' ings that when a special key is operated its pin 5 will enter its respective slot 57 and thus contact with one of t e incline walls of said action will brin the solid portionsof the periphery of said segment 'into aliiiement with the remaining pins and prevent thei'rf movement until the se ment has returned to o'sition. pins are guided in slots 58 formed in a sta tionary se ment 59 which is secured in position outsi e of the segments 41 and 56 by the aforesaidjscrews '42.

By theneculiar constructions above described I am enabled to secure a large special indication of the character oithe transaction in connection with the indication of the amount. Further the settingof the special indicator also results in a similar setting of -the special printin segmentwhereby the de- -t ail strip and chec receives a record of'the nature ofjeach s ecialtransaction.

Having thus eseribed my invention what I claim as new and desire to secure by Letters Patent is and the key detent.
